Area Forecast Discussion
National Weather Service Taunton MA
128 PM EDT Tue Jun 27 2017
.SYNOPSIS...
A strong jet stream will result in widespread afternoon showers
and thunderstorms across Massachusetts, Rhode Island and
Connecticut. A few of the storms may contain gusty winds and
small hail. A warming trend begins for the latter half of the
week with a return to summer heat and humidity Friday and
Saturday. A warm front may bring some showers and some
thunderstorms Thursday night, with more showers and
thunderstorms possible Friday through the weekend.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Expect periods of sun much of the afternoon that will allow for
some solar heating. Temps at the top of the mixed layer will be
8-10C or its equivalent, so we expect max sfc temps 75-80.
We continue to watch the potential for strong thunderstorms this
afternoon/evening. Morning soundings show an elevated dry
adiabatic lapse rate reaching 700 to 750 mb, 850 mb winds around
25 knots, and 500 mb winds 50-60 knots. Cold temperatures aloft
are giving us stability parameters favorable for convection.
Synoptically, A sharp upper trough is moving through the Eastern
Great Lakes with a 120-knot upper jet moving around the base of
the trough and across New England. Our area will mainly be on
the left entrance region of the jet rather than one of the more
favored areas for upper venting. Wet bulb zero values this
morning ranged from 6700 feet at Albany to 8800 feet at
Brookhaven NY...Gray ME and Chatham were 7300-7400 feet. We
note SPC has areas west of I-95 in a Marginal Risk for severe
weather. Considering all of this, we will maintain some enhanced
wording for strong winds and small hail in the forecast.
Observed winds aloft in the projected mixed layer this morning
were 20-25 knots. Model guidance forecasts a range of 20-30
knots during the afternoon. Expect afternoon wind gusts of 20-25
knots, with some potential for gusts of 25-30 knots.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
Tonight...
Cyclonic flow continues along with cold temps aloft and 40-45 kt of
deep layer shear. This will support leftover showers and isolated T-
storms to persist into the evening (especially over RI and eastern
MA) before taping off after midnight. Patchy fog possible given
leftover low level moisture from earlier storms
Wednesday...
Mid level flow is still cyclonic however flow becomes more WNW which
results in column drying out along with surface dew pts falling into
the 40s. Cyclonic flow aloft combined with cold temps will yield
plenty of diurnal clouds and the risk of an isolated shower/T-storm.
However given lack of moisture areal coverage should be limited to
isolated. Otherwise a fairly nice day by late June standards with a
mix of sun and clouds, highs 75-80 along with comfortable humidity
with dew pts in the upper 40s and low 50s!
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Highlights...
* Thunderstorm chances increase Thursday night through Sunday
* Heat and Humidity return Friday, lasting into the weekend
Pattern Details...
00z guidance is in general agreement synoptically with some
difference in strength and timing for each wave late in the week.
Upper level trough axis will begin to push offshore on Wednesday
resulting in a quasi-zonal flow for the region beginning on
Thursday. The upper level pattern will become more amplified by the
weekend resulting in a broad trough over the Great Lakes with sub-
tropical ridge building over the weekend. Because of the ridging
over the East Coast and the Midwest trough, a cold front will be
come nearly stationary with very little eastward progress this
weekend. Ridging out West by Sunday will push towards the Great
Lakes by early next week, pushing the broad upper level trough over
the Northeast.
Details...
Wednesday night into Thursday...
Surface high pressure over the region Wednesday night will help keep
winds light and skies clear. Overnight lows will drop into the mid
to upper 50s with metro regions in the 60s.
Dry day to start on Thursday as high pressure will slide offshore.
The flow will turn more active with zonal flow aloft and a few weak
waves passing through. Impressive warming aloft as surface warm
front pushes through the region. This will push southern New England
in the warm sector resulting in increasingly warm and humid
temperatures.
A weak shortwave will move through the flow Thursday evening/night.
With zonal pattern and both 850mb isotherms and winds becoming
parallel, appears that anything the fires across upstate NY will
ride through the flow moving into the area. In fact, guidance is
indicating a lingering MCS will move through the flow late in the
afternoon/evening which could result in a few strong storms, esp
north of the Pike. However, new convection could refire along its
southern edge given the strong low level jet and moisture over the
area. Trends will have to be watched.
Depending on the outcome of convection and cloud cover,
temperatures will remain in the low 80s. But it will feel warmer as
humidity will be on the rise. Showers and thunderstorms will
continue during the overnight hours keeping temps in the upper 60s.
Friday into Sunday...
Unsettled weather pattern for this time period as southern New
England remains in the warm sector with heat and humidity. 850 mb
temps warming to 17-18C as well as southwesterly flow, will allow
for the summer heat to returns to the region. Appears that the
potential for 90 degrees is possible on Friday and Saturday as the
back door cold front continues to remain well north of the region.
Heat headlines may be needed as 70F dewpoints beginning to pool into
the area.
There remains a chance for showers and thunderstorms each day, but
difficult to place the exact timing and location of any strong
storms due to lack of surface boundary. Daytime heating will allow
for scattered showers and thunderstorms to develop on Friday.
Another shot for scattered showers and thunderstorms will develop on
Saturday, but western locations have the better shot thanks to
approaching pre-frontal trough. Lower confidence for eastern
locations as subtropical ridge will build in pushing a dry slot into
the area on Saturday. Cold front will approach on Sunday triggering
another round of showers and thunderstorms for southern New England.
Through this period, the potential for strong to severe weather
appears possible as the region remains in the warm sector. Plenty of
instability and moisture will continue to pool into the area with 0-
6 km shear values around 30 kts. Main risk will be strong gusty
winds as well as heavy downpours as PWATs will be above 1.5 inches.
Still uncertainty with this portion of the forecast so stay tuned
for updates.
Monday...
Cold front will slowly pass through the region on Monday, however is
appears that it may get hung up. Cyclonic flow aloft with southwest
flow in the mid-levels may trigger another round of showers for the
area. Low confidence on this portion of the forecast as there is
still a spread in the guidance.
